plant comprises three 46 metre high boilers of the once-through type. Russian coal is the main fuel, while oil is normally used as the starting fuel. Saw dust is also added to coal, which accounts for at the most 2% of the energy. The Naantali 2 boiler was supplied in 1964 by Gebr. Sulzer AG, and turbogenerators by Kraftwerk Union of Siemens.
Cement production is an energy-intensive process consuming thermal energy of the order of 3.3 GJ/tonne of clinker produced. Electrical energy consumption is about 90 – 120 kWh/tonne of cement (Giddings, et al, 2000; European Commission [EC] 2001). Historically, the primary fuel used in cement industry is coal.

Cement plant is necessary for cement production, mainly consist of a series of cement equipment apply for preparation of cement raw materials, clinker production, and finished cement production, such as cement mill, cement crusher, rotary kiln, cement roller press, cement dryer, clinker cooler, cement silo, and related cement plant equipment.
Applied to clinker, it is calculated as: LSF=CaO/ (2.8SiO 2 + 1.2Al 2 O 3 + 0.65Fe 2 O 3) Often, this is referred to as a percentage and therefore multiplied by 100. The LSF controls the ratio of alite to belite in the clinker. A clinker with a higher LSF will have a higher proportion of alite to belite than will a clinker with a low LSF.
